I just booked a journey on Eurostar from Brussels to London on a Saturday evening, departing Brussels at 20:22, in Standard class. It's the last train of the day.
I realized after booking that the last train on a Saturday evening could have a lot of rowdy passengers - e.g. people who came across the channel for a day of partying and are heading home, possibly noisy / drunk / unruly / etc. That's not particularly the travel experience I'm looking for. Is this to be expected?
If so, would it help to upgrade to Standard Premier?
